perfmonitor处理器是性能监控工具、允许使用者跟踪事件频4选择一套模式具体名单.同时CPUID的作者出的软件

PerfMonitor is a processor performance monitoring tool. It allows to track the frequency of 4 events choosen in a set of model-specific list.

PerfMonitor can be used to identify the performance bottlenecks of a system, or to monitor a program for cache-miss rate or mis-predicted branches. But PerfMonitor can also be used as a hardware-level CPU comparison tool, comparing the key parameters of different CPUs runnning the same benchmark
